| Summary | 0010317: Freezing when resizing windows in i3wm | ||||
| Description | I don't know that this is related to using a tiling window manager; it just happens to be what I use on my desktop and the environment I'm most often in. I haven't seen the same behavior in a DE like Cinnamon, but I spend very little time in such an environment unless I'm on my laptop. There are certain combinations of window resizing that causes Ardour9 to freeze. Once it happens, I can get it to crash multiple times in a row, but I haven't yet found a single set of steps to reproduce. I created a video to demonstrate: https://youtu.be/ES9rkOifqwk | ||||
| Additional Information | Based on the circumstances under which I reproduced the error today, it almost seems like a math issue when resizing: Ardour is freezing when I have 3 equally-sized app windows, but not with 2. Is it possible that i3 is sending float pixel sizes when Ardour is expecting integers? I also found that the exact same circumstances wouldn't cause a crash if I was running at a different resolution. I haven't seen this happen in Ardour8 (which I test in the video), but I haven't spent as much time in 8. System: Ardour 9.2, Debian 12, i3 window manager | ||||

I had a bit of an epiphany while recording the video. I can now reproduce this issue very consistently, even after a system restart. Every time my window manager tries to divide the screen into 3 equally sized windows, Ardour9 freezes. Since my previous freezes occurred while resizing by dragging the edge of an app window, I hadn't made the connection. |

Looks like the WM does not heed the minimum window size that Ardour announces. |
|
|
Yeah, the WM definitely ignores min window size, but I've had the windows much smaller than 3440/3 px without any issues. It seems like only really specific circumstances cause the issue. Do you think that ignoring the min window size could cause such a freeze? Also, do you think that trying to replicate this with the debug version would yield answers? |
